Question

The Perimeter of a rectangle is 304 cm. The length is 40 cm longer than the width. Find the length and width.

Answer 1

Step-by-step explanation:

Perimeter = 2(length) + 2(width)

let x represent the width

$304 = 2x + 2(x + 40)$

$304 = 4x + 80$

$224 = 4x$

$x = 56$

this means that the width is 56cm

sub this into the length:

length = 56 + 40

= 96cm
